What version are you looking for? PC 3.5", 5.25", Amiga, or something else? I was able to find the complete set of Amiga Miracle software online, and even jury rig a cable for it (well I mean cleverly route 2 jumper wires and press the keyboard up to the back of the Amiga
).
Unfortunately, I've got everything but the disks, original packaging, & the sustain pedal with me at the moment. That stuff is probably at my mom's house, but I don't think I can make it over there to fetch the disks until after next weekend.
